Considerations & Trade-offs

  • Designed for single-stack magazines only, so it is not a fit for double-stack magazine setups.
  • Magazine retention is handled by a built-in tension spring, which supports secure carry but may require a specific fit preference for smooth draw and reholstering.
  • The curved, slimmer-profile design is intended for waistline carry, which may be less suitable if you prefer a bulkier or more rigid mag carrier.
  • Compatibility is listed for 9mm/.40 cal/.45 cal/10mm/.357 Sig magazines, so fit should be checked against your exact magazine dimensions before purchase.
